Could someone tell me what is the Arcgis cokriging equation? I can only find the simple equation which is:

Z1(s) = µ1 + ε1(s)

Z2(s) = µ2 + ε2(s)

When I use SAS to do the cokriging analysis, it's more accurate than using Arcgis. So I want to compare the difference between each equation.

Many thanks,

What criteria are you using to say that SAS is more accurate? Are you using the default model and comparing crossvalidation results?
